Chapter 2: Using Modularization to Handle Complex Projects
When you start programming in Python, it is very tempting to put all your program code in a single file. There is no problem in defining functions and classes in the same file where your main program is. This option is attractive to beginners because of the ease of execution of the program and to avoid managing code in multiple files. But a single-file program approach is not scalable for medium- to large-size projects. It becomes challenging to keep track of all the various functions and classes that you define.
To overcome the situation, modular programming is the way to go for medium to large projects. Modularity is a key tool to reduce the complexity of a project. Modularization also facilitates efficient programming, easy debugging and management, collaboration, and reusability. In this chapter, we will discuss how to build and consume modules and packages in Python.
We will cover the following topics in this chapter...
